Correction: Extended state observer-based integral sliding mode control for an underwater robot with unknown disturbances and uncertain nonlinearities (IEEE Transactions on Industrial Electronics (2017) 64:8 (6785-6795) DOI: 10.1109/TIE.2017.2694410)

The purpose of this note is to correct the matching condition and stability proof in [1]. While the main results are unchanged, there should be some consequent modifications, which are shown in detail as follows: First, [1, eq. (14)] should be modified as (equation presented). and the time-varying matrix φ can be defined as (equation presented) where (equation presented) are scaled estimation errors. Due to the added term φ, [1, eq. (23)] can be corrected as (equation presented) Substituting [1, eq. (18)] into (3), we have (equation presented) Furthermore, [1, eq. (25)] should be updated as follows: (Formula Presented).
